My idea is that these could help some businesses by promoting their products, their services, their retail business and boutique coffees / coffee bar. It is powerful, interesting and noteworthy, could be used for publicity and promotions and as a takeaway for conferences and conventions which would be a reminder of that business for a long time.

Let me know.

This would be a great way to promote a business. They are interesting. They are collectible. They draw attention to the business and they are saved and shared with others, each time bringing attention to whatever businesses are using them.
